An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Clinical safety issues of measles, mumps and rubella vaccines

Bulletin of the World Health Organization, 2000
The clinical safety of measles and measles-mumps-rubella vaccines has been questioned in recent reports that propose a possible link between measles virus or measles vaccines and the occurrence of juvenile Crohn disease and autism.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Exploring Fusarium Biocontrol, drought Tolerance, and plant growth promotion by Bacillus strains from Cuban wheat varieties

Biological Control
Members of the Bacillaceae family are recognized for their ability to promote plant growth under drought stress and for their capability to produce bioactive metabolites displaying antagonistic activity against phytopathogenic fungi.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Sweetpotato whitefly: prospects for biological control

California Agriculture, 1992
The damage to desert agricultural crops in Southern California and Arizona in fall-winter 1991 by the sweetpotato whitefly, Bemisia tabaci (Gennadius) is unprecedented in the history of the South west.

Corynascella humicola, a root endophytic fungus from crabgrass, confers growth promotion and induced systemic resistance in gramineous plants

Biological Control
Root-habiting fungi have great potential for plant growth promotion (PGP) and induced systemic resistance (ISR) against pathogens. In the present study, we isolated a potentially beneficial fungus, Corynascella humicola CHDR1-1, from crabgrass roots ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
